Description

Brief indication: Device for winding an elongated, wire-shaped body on a winding body.

DESCRIPTION

The invention relates to a device for winding up and of a body built up of at least one elongated, wire-shaped strand on a winding body comprising a frame comprising at least: a supply of the elongated, wire-shaped body; a drivable winding body rotatable about a winding shaft, and wherein the device further comprises drive means for rotating the winding body rotatably.

In the fiber or yarn industry, the fiber or yarn (or generally an elongated, wire-shaped body) is wound onto a winding body, such as a spool, for further processing. The elongated, wire-shaped body can be composed of one or more strands. In specific applications, for example in the production of single-stranded plastic fibers by means of extrusion, which are used in the manufacture of an artificial grass sports field, it is desirable for the fiber to be unwound and twisted about its longitudinal axis.

This twisting technique is called "twisting" in an elongate, wire-shaped body composed of a single strand. The twisted single fiber is again wound onto a winding body after "twisting". An elongated, wire-shaped body composed of several strands can also be twisted about its longitudinal axis. This tordering technique is also referred to as "twisting".

It should therefore be noted that the device described in this application is suitable both for processing an elongated, wire-shaped body which is then composed of a single strand or of several (more than one) strands.

The compact but highly functional construction of the winding device according to the invention is further enhanced by the fact that the tensioning means comprise a rotating shaft rotatable by the driving means, which rotating shaft is mounted in the frame in such a way that a first end of the rotating shaft is and the other, second end of the tracking axis is outside the frame. The drive means can herein be located at least partially outside the frame and rotatably drive the second end of the rotation shaft. This last feature guarantees an easy to operate (read: drive) wrapping device. The twisting means are thereby easily accessible in the frame for the purpose of, for example, maintenance, but are furthermore not impeded by components such as the drive means forming part of the fixed world for an optimum twist or twisting operation.

In a specific embodiment, the winding body is mounted on the winding shaft and the winding shaft is connected to the first end of the winding shaft. In a specific embodiment, the winding shaft is in line with the tracking shaft 20. With the aforementioned aspects, a mechanical freewheel or uncoupling is guaranteed between the winding body and the winding shaft on the one hand and between the winding shaft and the winding shaft on the other hand. This guarantees that the winding shaft is accommodated in the frame with free bearing and functioning as a semi-fixed world, while in the latter aspect on the one hand a compact construction is obtained, but moreover is made possible by this same mounting means by this mounting drive.

In a very specific embodiment with which very effectively any number of twists (twists or twists) can be arranged in the elongated, wire-shaped body per unit length, the winding device according to the invention is 1024504

In order to further reduce wire breakage due to wear, according to the invention the bore in the shaft of rotation is provided with friction-reducing means, which means may comprise one or more ceramic guide surfaces arranged in the bore.

In a special embodiment which provides a compact, light but in particular very functional design of the present invention, it is characterized in that the winding shaft is provided with a support on which the drive means for the winding body are placed. The support can herein be composed of a first support shaft connected to the winding shaft and a second support shaft pivotally connected to the first support shaft.

With a very simple but reliable design of the drive means for the winding body, these comprise a drive roller which is rotatably mounted on the second support arm and can be placed against the winding body. This method of driving the winding body for the purpose of winding up the twisted or twisted elongated, wire-shaped body offers, as stated, not only a compact but also an inexpensive construction.

Accurate winding of the elongated, wire-shaped body on the winding body is ensured in accordance with the invention in that the drive roller can be placed against the winding body by means of force means with an adjustable constant force, and wherein optionally the force means comprise a gas or tension spring.

In order to ensure a good spread of the windings of the elongated, wire-shaped body over the entire length of the winding body, according to the invention, the second method is based on the second

embodiment of a wrapping device according to the invention. The I

device 1 Is made up of a frame 10 made up of different I

uprights and beams. All specific parts of the wrapping device I

according to the invention are built around a shaft 7, which I

that a first end 7a of the shaft 7 (not shown) into the I

interior of the frame 10, while the other second end 7b of I

the shaft 7 as shown in Figure 1 is located outside the frame. The I

second end 7b of the shaft 7 is designed as a pulley over which an I

An endless carrier, for example a V-belt, can be brought, which endless I

carrier is placed over a drive shaft of the drive means 2. The I

drive means 2 which can be, for example, an electric motor is outside the I

frame 10 connected to the fixed world and penetrates during operation I

of the winding device according to the invention, a rotational movement I

frame 10 and the parts disposed therein are more accessible to I

maintenance, repair or exchange of the winding body 5 with the I

wound elongated, wire-shaped body 8. I

Figure 2 shows the construction of the I in more detail

30 wrapping device according to the invention and the relevant parts I

shown. In the figures 3a-3f the construction of the I

9 shows the device from several different views. A per se known part of the winding device according to the invention relates to the winding shaft 6 (figures 3a-3c) on which a winding body 5 can be mounted. The winding body 5 is therefore freely rotatable about the winding shaft 6.

For the sake of safe securing / locking of the winding body 5 around the winding shaft 6, the free end 6b of the winding shaft 6 is secured by means of a nut or locking bolt 9, which prevents the winding 1 body 5 from slipping.

The core of the invention is the provision, prior to winding up the elongated filamentary body 8 around the winding body 5, in the elongated filamentary body to make one or more turns (twists or twins) per length unit. According to the invention, the winding device is provided with twisting means which, prior to winding the elongated, wire-shaped body 8 (plastic fiber or yarn) onto the winding body 5, one or more twists for an elongate, composed of one strand, insert a filamentary body or "twisting" into an elongated, filamentary body formed from one strand in the body.

The core part of the tracking means relates to the tracking shaft 7 already shown in Figs. 1 and 2, which is driven with the free end 7b via a belt or pulley transmission by drive means, for example an electric motor. A freewheel clutch 7c can be arranged between the tracking shaft 7 and the belt pulley 7b.

The tracking shaft 7 is mounted in the beam 10a of the frame 10 (see figure 1), such that the end 7a of the tracking shaft 7 extends into the frame 10. Arranged on the first end 7a of the tracking shaft 7 is a tracking arm 11 which extends radially from the tracking shaft 7. The twisting arm 11 is provided with a free end 11a and a plate part 11b serving as a counterweight.

I feed-through channel 13, which feed channel 13 extends longitudinally from the I

The guide opening 12 extends as far as the twisting arm 11 on the first I

11 direction. In this embodiment, the guide means 38a-38b are designed as a circular tube with a radius much greater than the maximum radius that the winding body 5 can reach with the windings 8. More specifically, the outer radius of the guide ring 38a-38b is at least equal to the length of the twisting arm 11 as seen in the radial direction.

During the rotational movement which the twisting arm 11 undergoes together with the twisting shaft 7, the elongated, wire-shaped body is pulled over the guide ring 38a, so that a jamming of the device and a possible thread breakage is prevented.

Figure 3f shows another embodiment of a wrapping device according to the invention, wherein instead of one guide ring 38a two guide rings 38a-38b are used, with which the formation of balloons in the elongated, wire-shaped body and a jamming of the device and a possible wire breakage is prevented.

As shown in Figs. 5a-5b, the wire-shaped body carried through the guide opening 12 and through the feed-through channel 13 of the turning arm 11 is guided through a bore 32, which bore 20 is arranged in the turning shaft 7. To facilitate the transition between the vertically oriented feed channel 13 (on the warp arm 11) to the horizontally extending bore 32 in the first end 7a of the warp shaft 7, the bore 32 connects to the feed-through channel 13 via a right-angled portion 32a.

As clearly shown in Figures 5a and 5b, the first end 7a is freely rotatably connected by means of bearings 29 to the semi-fixed world, which semi-fixed world is represented by the flange 35 of the winding body 1 and the hereafter support 18 to be explained with support arms 18a and 18b.

Due to this construction, the winding shaft 6 is freely movable in the frame 10 relative to the tracking shaft 7.

1024504

12 I

As clearly shown in Figure 5a, the flange 35 is from I

the winding shaft 6 also provided with a bore 32 which at the location of I

the reference numeral 32b connects to the bore 32. The bore 32 in the I

winding shaft 6 also has a right angle so that the bore 33 opens out I

5 on the outlet opening 34, which outlet opening 34 is arranged in the I

surface of the flange 35 of the winding shaft 6. Because the winding shaft 6 I

together with the flange 35 and the support 18, 18a-18b are stationary (semi-fixed I

world) relative to the rotating shaft axis 7, the bore I

32 additional claims (twists or twists) in the through hole I

10 32 lined wire-shaped elongated, wire-shaped body are I

applied. The elongated, wire-shaped I coming out of the outlet opening 34

body is now provided with a number of claims (twists or twins) I

per unit length and now serves in multiple turns 8 on the I

wrap body 5 to be wound. I

With reference to Figures 3a, 3c, 3d and more in I

detail 3f, the elongated, wire-shaped body via a number I

guide wheels 19 guided to a guide element 17, before the I

elongated, wire-shaped body in the winding groove of the guide roller 16 I

is included for the winding 1ng of the wire-shaped I

20 body around the wrap body 5. I

The elongated, wire-like body of the I runs thereby

last guide wheel 19 over a guide disc 39a of an I

wire release device 39 in the direction of a pigtail shape I

curved, eye 19 '. The guide disc 39a is provided with a groove I

25 (for example a flat or V-groove) for receiving the elongated, I

wire-shaped body and is connected via a magnetic coupling (not shown) I

driven by a rotatable shaft (not shown). This magnet I

coupling works according to the principle of eddy currents. This axis 1s through I

the wire release 39 and is fed via the gear transmission 24, I

25, 26 and via the first gear transmission 21, 22, 23 through the I

drive shaft 7 driven. I

1024504_I

13

The direction of rotation of the gel disc 39a is in the conveying direction of the elongated, wire-shaped body. Due to a suitable transmission ratio of the above-mentioned gear wheel transmissions, and also due to the magnetic coupling, the guide disc 39a has a higher turnover speed than the transport speed of the elongated, wire-shaped body through the device. As a result, the wire release 39 is capable of reducing any elongation present in the elongated, wire-shaped body. This keeps the hardness of the coil constant. A coil wound with very high wire tension leads to a hard coil.

The guide roller 16 (see Figs. 3b and 3f) is provided with a winding groove spiraling over the surface of the jacket for winding up the elongated filamentary body uniformly over the full length dimension of the winding body 5.

For the purpose of winding up the elongated wire-shaped body around the winding body 5, the drive means comprise a drive roller 15, which can be placed against the winding body 5. The force with which the drive roller 15 presses against the winding body 1 and the windings 8 (see Figs. 2, 3b, 3c, 3e) is adjustable and, for example, adjustable by means of a gas or tension spring 20.

The drive roller 15, the guide roller 16 and the guide element 17 are mounted on a second support arm 18b, which support arm 18b is pivotally connected to a first support arm 18a. As already noted above, the support arm 18a is mounted on the first end 7a of the shaft of the shaft 7 by means of bearings 29.

The entire structure, comprising the support 18 (first support 18a and second support 18b) together with the drive roller 15, the guide roller 16 and the guide element 17, is floatingly accommodated in the frame 10. The winding shaft 6 is mountable with the aid of the flange 35 on the first supporting shaft 18 serving as a semi-permanent world. To this end, the first supporting shaft 18a is provided with a number of fixing openings 37 which 1024504

14 I

serve for receiving fixation pins 36 for the purpose of I

attachment of the winding shaft 6 with the first support arm 18a. Like the I

5a and 5b clearly show, the winding body 5 is with the aid of I

the bearings 30 are mounted on the winding shaft 6. I

The drive of the drive roller 15 and the guide roller 16 I

for winding up the elongated, wire-shaped body about I

the winding up body 5 takes place as follows. The first end 7a of the I

The rotation shaft 7 is provided with a circumferential I near the rotation arm 11

toothing 21 (see Figs. 3b, 3d, 3f, 5a and 5b) over which a toothed belt 23 I

10 is provided for driving a first sprocket 22 mounted on the I

first support arm 18a is provided. I

A toothed belt becomes I via different toothed belt transmissions

28 driven (see figure 3e), which toothed belt 28 drives the drive roller gear I

15a and the guide roller driving gear wheel 16a (see figures 3b, 3c, 3e) I

15 for rotatingly driving the drive roller 15 and the guide roller I

16. As a result, the adjustable pressing force (exerted by the I

gas spring 20) the drive roller 15 against the winding body 5 (and the already I

wound windings 8) for rotating I over the bearings 30

the wrapping body 5 (see figures 5a and 5b). I

The drive roller 15 pulls the elongated, wire-shaped body I

by the establishment. The elongated, wire-shaped body is connected via the I

feed opening 3 introduces the frame 10 in the direction of the I

rotary arm 11, which component is driven by the rotary rotary rotary shaft I

7 a circular movement in the frame 10 thereby makes it elongated, I

A thread-like body entrained over the ring 38a (38b). This I

circular movement of the twisting arm 11 is the first to contribute to the I

applying a number of claims (twists or twists) per length I

unity in the elongated, wire-shaped body. I

The wire-shaped body is guided through the guide eye 12 I

30, after which the wire via the supply channel 13 and the right angle I

bore portion 32a is passed through bore 32. It's elongated, I

1 0 2 4; δ I

The threaded body leaves the bore 32 via the right-angle winding shaft bore 33 and the exit opening 34. Because the ultimate opening 34 forms part of the non-rotating semi-permanent fixed world (consisting of the winding shaft 6 with flange 35, the first support arm 18a and the second support arm 18b) 5 creates the rotating twist shaft 7 in the bore 32, again turns (twists or twists) in the elongated, wire-shaped body.

After leaving the outlet opening 34, the then twisted, elongated, wire-shaped body is guided over a number of gelling wheels 19 before the wire-shaped body is guided over a guide element 17 and via the guide groove 16b of the guide roller 16 through the drive roller 15 around it. winding body 5 is wound.

As the figure 3d clearly shows, the guide ring 38a is mounted on the first support arm 18a. As an additional protection against the unexpected hooking of the balloon 15 of the elongated, wire-shaped body generated by the warp arm 11, a second guide ring 38b can be used over which the elongated, wire-shaped body can be guided before the wire-shaped body is guided via the guide eye 12 and the passage channel 13. in the direction of the tracking shaft 7. The use of a second guide ring 38b considerably improves the functioning of the device, because short-term instability of the balloon prevents the elongated, wire-like body from becoming entangled in the drive structure (the rotating parts).

In order to prevent wear of the elongated wire-shaped body, the guide eye 12 and / or the supply channel 13 can be provided with a material with an increased hardness. More in particular, the guide eye 12 and the supply channel 13 can be provided with ceramic contact surfaces. Supply channel 13 is designed as a slot in Fig. 4, but it is also possible to design a bore in the taper arm 11.

A slot 46a is provided in the support plate 46. The I

The position of the brake wheel 42 in the slot 46a is adjustable, so that the I

This is in contrast to the coil body 44, which can rotate freely about its axis 44a. The magnetic brake 51 is braked by means of the eddy current principle on the elongated wire-shaped body arranged in windings in the grooves 45'-44 '5 when the coil body 45 runs down towards the inlet opening 3, resulting in an adjustable internal thread tension.

The brake 51 can also be designed as a speed-dependent hysteresis brake, i.e. the braking action is dependent on the speed of the device. The higher the speed, the greater the braking effect of the brake 51 on the elongated, elongated, wire-shaped body. A more stable balloon is hereby achieved over the entire speed range of the device.
